Studies of Adsorbed Species of CO, H2 and CO/H2 over ZrO2

Abstract

Abstract: The adsorption of CO, H₂ and CO/H₂ on ZrO₂ was investigated by in situ FTIR. H₂ species adsorbed over ZrO₂ produced two bands at 3780 and 3680 cm^-1, corresponding to ZrOHZr and ZrOH, respectively. COadsorbed on ZrO₂ formed formate species at 200 ℃, which slowly decomposed to COwith the rise of adsorption temperature. The formate over ZrO₂ could be hydrogenated into methoxide species and methane in H₂. As a result, the hydrogenation of methoxide, which proceeded slowly relatively, seemed to be the rate-determining step.

Key words: in situ FTIR, H₂, CO, Adsorption
